And if you don't initiate divorce you will also highly likely end up divorced. Don't make decisions about filing for divorce based on hopes she'll return - make it based on the business of protecting your assets. Some situations call for filing, other situations call for simply implementing natural consequences of their decisions. But I do recommend consulting a lawyer just to find out how to protect yourself financially and what the likely outcome would be if you do divorce. Don't make any big decisions like moving out until you have consulted with a lawyer to see if it would hurt you in a divorce.
